Introduction: Tesla’s Defining Moment Across Three Continents
Tesla closed 2025 with a series of developments that underline its unique position in the global electric vehicle and autonomous driving race. From a highly praised real-world Full Self-Driving (FSD) test on South Korean highways, to market dominance in Norway’s record-breaking EV year, and a powerful late-year rebound in China, the company demonstrated both technological maturity and commercial resilience. Even as debates continue around pricing, regulations, and design choices—such as the controversial Cybertruck interior—Tesla’s influence across mobility, automation, and consumer behavior remains difficult to ignore.
the Original
Tesla’s Full Self-Driving system recently received strong praise from the Korea Expressway Corporation after undergoing an extensive real-world test on December 15, 2025. Conducted from 10 a.m. to 6 p.m., the evaluation included four occupants in the vehicle, among them the head of the mobility department. All four FSD driving profiles, ranging from “Sloth” to “Mad Max,” were tested across a mix of highways and dense urban areas.
The routes included major highways such as Gyeongbu, Cheonan, and Cheonan–Nonsan, as well as city roads in Dongtan New Town, Sejong Special City, and Daejeon Metropolitan City. Since FSD in South Korea is currently limited to imported Model S and Model X vehicles from the United States, the test did not involve the more common Model 3 or Model Y.
According to the report shared on Naver Cafe, Tesla’s FSD performed impressively in both urban and highway environments. Testers noted that in city driving, the system already exceeds the skill level of average human drivers, except in a few challenging scenarios such as unprotected left turns and complex construction zones. On highways, FSD was rated “excellent,” with smooth lane changes, confident merging, and stable autonomous behavior.
However, the system was not without flaws. Testers observed frequent violations involving local bus lanes and posted speed limits. Interestingly, FSD sometimes appeared to follow the natural flow of traffic rather than strictly adhering to traffic rules, a behavior that may reflect Tesla’s AI-driven approach to real-world driving dynamics. These issues were described as software-level problems that could likely be resolved through future updates.
Beyond South Korea, Tesla also dominated headlines in Norway, where the country set a new all-time car sales record in 2025 with nearly 180,000 new registrations. A rush to purchase EVs ahead of a post–New Year VAT increase of roughly 50,000 Norwegian kroner (about $4,650 USD) pushed demand forward. Electric vehicles accounted for an astonishing 96% of all new car sales.
Tesla captured approximately 19.1% of Norway’s total market with 34,285 registrations, far ahead of competitors like Volkswagen and Volvo. The Model Y alone represented 15.4% of the entire Norwegian car market, while the Model 3 also ranked among the top five best-selling vehicles.
In China, Tesla ended the year on a strong note by selling 97,171 vehicles wholesale in December, its second-best monthly result ever. While full-year wholesale sales declined by 7.08% to 851,732 units, December’s performance suggested renewed momentum, partly driven by buyers taking advantage of favorable tax policies before year-end. Gigafactory Shanghai continued to serve as Tesla’s most important production and export hub.
Finally, attention turned to the Tesla Cybertruck, where one owner modified the interior to add a front bench seat—an idea originally shown at the 2019 unveiling but abandoned in production. While the modification drew interest, it raised safety and regulatory concerns, especially due to the lack of a central airbag. Cybertruck sales have lagged expectations, largely due to pricing. Originally announced at $39,990, $49,990, and $69,990, the vehicle launched at prices exceeding $100,000 USD, pushing many early reservation holders out of the market.
What Undercode Say:
Tesla’s recent developments reveal a company operating on multiple strategic fronts at once—software leadership, market penetration, and brand experimentation—while still grappling with the limits of regulation and affordability.
The South Korean FSD test is particularly significant because it represents a government-adjacent, real-world evaluation rather than a controlled demo or internal benchmark. The fact that testers described Tesla’s system as outperforming average human drivers in most urban scenarios is a strong endorsement of Tesla’s vision-only, AI-first approach. Notably, the observation that FSD sometimes prioritizes traffic flow over rigid rule compliance highlights a philosophical divide in autonomous driving: strict rule-following versus adaptive human-like behavior. In practice, real drivers often bend rules to maintain safety and efficiency, and Tesla’s system appears to be learning that nuance.
However, this same behavior could become a regulatory flashpoint. Bus lane violations and speed limit inconsistencies may be tolerated in testing, but they are unlikely to be acceptable in widespread deployment without clearer safeguards. This puts pressure on Tesla to localize its autonomy stack more deeply for each market, especially in countries with strict traffic enforcement like South Korea.
Norway’s numbers tell a different, but equally important story. Tesla’s nearly 20% market share in the world’s most EV-saturated country is not just a sales win—it’s proof of brand gravity. Achieving that level of dominance with a relatively small lineup suggests that Tesla benefits from a powerful feedback loop: strong charging infrastructure compatibility, high resale confidence, and consumer trust built over a decade. The Model Y’s performance shows that practicality, efficiency, and software integration now matter more to buyers than novelty.
China, meanwhile, remains Tesla’s most complex battlefield. The December rebound demonstrates that Tesla can still compete effectively when pricing, incentives, and production align. Yet the year-over-year decline underscores the reality of fierce domestic competition and razor-thin margins. Gigafactory Shanghai’s role as both a production and export hub is now critical not just for volume, but for Tesla’s global cost structure.
The Cybertruck situation highlights Tesla’s weakest point: expectation management. The gap between promised pricing and real-world costs has damaged trust among early supporters. While creative owner modifications show strong community engagement, they also reveal unmet demand for practicality and familiarity in a vehicle that was designed to be radical. A future refresh that balances innovation with everyday usability could help the Cybertruck find its footing.
Taken together, these stories show Tesla less as a single-product company and more as a global experiment in how software, manufacturing, and consumer psychology intersect. The company’s biggest challenge in the coming years will not be technology—but alignment between ambition, regulation, and affordability.
Fact Checker Results
The South Korean FSD test date, routes, and evaluation details align with the Korea Expressway Corporation report.
Norway’s 2025 sales figures and Tesla’s market share are consistent with industry and OFV statements.
Tesla China’s December wholesale numbers and full-year decline match CPCA-reported data.
Prediction
Tesla is likely to accelerate localized FSD updates in Asia to address regulatory concerns while pushing for limited supervised autonomy approvals. In Europe, especially Norway, Tesla’s dominance will pressure competitors to cut prices or risk irrelevance. In China, short-term rebounds will continue, but long-term success will depend on aggressive cost control and faster model refresh cycles.
